Drum system comprising multiple horizontal bars

ABSTRACT

A drum to be used in textile finishing operations has a body and a helical wrap surrounding the body from the middle part to the ends thereof. The drum has a plurality of bars arranged at certain intervals determined according to the requirements of the process.

THE RELATED ART

The invention is a drum system designed for use in textile finishingoperations for the purposes of eliminating the tension of the processedfabric, softening, correction of grains, increasing frictionalresistance, and eliminating production dust.

The invention particularly relates to a drum system comprising aplurality of horizontal bars arranged in certain intervals determinedaccording to process requirements and a helical expander wrapsurrounding said horizontal bars.

THE PRIOR ART

Up until today, drums used in textile finishing machines generally havecircular or elliptical cross-sectioned structures. Circularcross-sectioned systems mostly make use of the continuity of rotationalmotion and perform the function of expanding the fabric. However, sincethey do not have strike effect, their area of usage is only limited toexpanding the width of the fabric. In the patent with application No.2008/04495, even though an elliptical sectioned drum is used instead ofa circular sectioned one, it is experienced that, since the planar andfull surface around the section cannot perform effective beating on thefabrics due to lubricity and the fabric couldn't be beaten adequately;the expected reaction couldn't be obtained. Drums called as beatercylinders and subjecting the fabric only to beating motion are alsofound. Said systems cannot perform the expanding activities. Also,nowadays, structures that provide volume and touch to the fabric byapplying distortion and bulking on the fabric via mechanical andpneumatic mechanisms are also found. However, these mechanisms do notprovide an expanding effect on the fabric and causes formation of faultsat the folding parts of the processed fabric.

It is also not possible with the prior art methods to ensure teasellingof piles and correcting the pile directions in fabrics that comprisepiles. At the same time, the prior art structures are also not useful interms of strength, and it is not possible to achieve long drum lengthsand high operating speeds required for processing wide products.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a drum mechanism developed foreliminating the above said drawbacks and bringing new technicaladvantages to the relevant technical field.

The main purpose of the invention is to softening the tension of textileproducts, giving volume by fluffing up, cleaning dusts due toproduction, and performing the striking operation with high efficiency,which cannot be performed with adequate efficiency in the prior artsystems. Instead of the lubricious planar structure found at the sectionin the prior art, horizontal bars having adjusted intervals betweenthereof according to process requirements cause extra bending among thebars by giving multiple linear strikes to the fabric, and thus provide adeeper operation on the fabric. In this way, it increases the beatingeffect on the fabric made by the drum. This extra beating effectgenerated eliminates the tensions caused by the weaving and knittingprocess in fabric construction and provides the product with a permanentand superior softness.

Another purpose of the invention is to ensure teaselling of piles andcorrecting the pile directions in fabrics that comprise piles. Thedirecting effect of the plurality of horizontal linear strikes in pileextension direction or against this direction ensures correcting thedirections of the piles and also provides them with a permanentlyvertical or horizontal position. Moreover, corrected piles provide theweaving or printing patterns on the product with a clearer appearance.

Another purpose of the invention is to meet the demand for the long drumsize required in processing of wide products and eliminate the drawbacksoccurring due to short drum size. The use of a plurality of horizontalbars instead of a planar structure around the circular or ellipticalsection allows increasing the drum strength and made it possible toproduce longer drums to process wider products. At the same time, italso allows reaching high operating speeds where the old systems are notadequate.

One of the significant advantages of the invention is to increase thefrictional resistance of the products when the extra softness, bulkingup and weaving or knitting construction improvements are combined.

In order to achieve the above said purposes which would be understoodbetter with the below given detailed description, the invention relatesto a drum to be used in textile finishing operations, comprising a bodyand a helical wrap surrounding the body at certain intervals. Said drumcomprises a plurality of bars forming said body and preferably providingan elliptical or polygonal geometry by being arranged at certainintervals determined according to the requirements of the process.

Another preferred embodiment of the invention comprises fixing plates onwhich said bars of the body are connected.

In another preferred embodiment of the invention, it comprises at leastone shaft providing rotational motion by transferring the motion itreceives from a drive unit to the body.

For better understanding of the embodiment of the present invention andits advantages with its additional components, it should be evaluatedtogether with below described figures.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the novelty according to the invention isonly disclosed for better understanding of the subject without formingany limiting effect.

FIG. 1 is a perspective view of the drum (10) according to theinvention. Accordingly, the drum (10) basically comprises a body (11),horizontal bars (112) forming said body (11) and preferably arranged atintervals along an elliptical or polygonal geometry, and a helicalexpanding wrap (13) surrounding said horizontal bars (112). Along thebody (11), fixing plates (111) are found where the horizontal bars (112)are mounted at certain intervals. In order to ensure the drive androtational motion of the drum (10), shafts (12) are found, whichtransmits the motion it takes from a drive unit to the drum (10).

The drum (10) performs rotational motion by means of the shafts (12)found at the center and at both sides of the body (11). A plurality ofhorizontal bars (112) are connected to fixing plates (111) in a way thatthey can provide an elliptical or polygonal geometry and have a distancebetween thereof determined according to the requirements of thepreferably.

The horizontal bars (112) arranged at intervals so as to form anelliptical or polygonal-formed section can provide multiple horizontallinear strikes on the fabric and can impact deeper on the fabric. At thesame time, as a result of the rotation of the drum (10), an increasedbeating effect is provided onto the fabric by applying extra bending tothe fabric among the bars (112). This extra beating effect is obtainedmore at the bars (112) that are found at the opposing narrow sides ofthe elliptical geometry structure.

Said expanding wrap (13) surrounds the body (11) from the middle part ofthe body (11) to both sides in the opposite direction of the rotation.While the horizontal bars (112) apply beating on the fabric, saidhelical expanding wrap (13) expands the fabric and keeps it opencontinuously during beating.

The drum (10) according to the invention can be used in tasks such astension elimination, softening, providing volume by bulking/puffing up,correcting weaving, knitting constructions and pile directions (grains),cleaning dusts caused due to material and production method, andincreasing frictional resistance of woven or knitted, plain or piledfabrics, carpets or textile products produced by methods other thanweaving or knitting in machines that perform textile finishing, byhaving the expanding and beating functions together.
